You are right to be concerned. Your brother is engaging in dangerous behavior. He is acting out aggressively. You also said that he is experiencing disturbing images and fantasies. Intervention is necessary.
I’m not sure what your role is in the family, or how much you can influence your brother but if you can convince him to see a therapist, then you should. He needs help.
There are several ways to approach this matter. Your parents should have him evaluated by a mental health professional. They can do this by asking a primary care physician for a referral. They can also contact the local mental health clinic or community mental health center and ask for an appointment. Having him evaluated is a first step, assuming that he is willing to cooperate.
If he’s not willing to cooperate, then you may have to approach this problem differently. For instance, when your brother was thinking about jumping off the top of the building, emergency services should have been called. That might have included 911 or a local mental health crisis team. Many communities have local mental health crisis teams who can come to the home, evaluate the situation and assist families in handling dangerous situations. Find out if you have a mental health crisis team in your community. You can do this by searching the yellow or white pages or by doing an Internet search. Enter the search terms [name of town] and “mental health crisis team” into the search engine.
If your brother is dangerous and is acting out aggressively, don’t hesitate to call the police. Understandably, you may be reluctant to do so but it’s important to protect your family and your brother when he is out of control. The police won’t necessarily arrest your brother. They may transport him to a psychiatric hospital for treatment.
I hope your family is able to get your brother the help he needs. Please take care.
